In a 7-quart Dutch oven (or a 7 quart soup pot), heat extra virgin olive oil over medium to medium high heat.
Add diced onion and poblano peppers, cooking until vegetables are softened and onions are translucent, about 3 minutes.
Add minced garlic and cook for 1 minute.
Add ground beef and sweet Italian sausage and brown completely, breaking up the pieces with a wooden spoon, about 7 minutes.
Add pinto beans (drained), black beans (drained), diced tomatoes (NOT drained), diced tomatoes and chilies (NOT drained), and beef broth. Stir everything together.
Add adobo sauce, tomato paste, bay leaves, and all of the Chili Spice Mixture. Stir to incorporate.
Bring the chili to a boil over high heat and then reduce to a simmer over medium-low heat. Simmer chili for 20 minutes, covered, stirring occasionally.
In the last 5 minutes, add the balsamic vinegar to the chili. Finish simmering for 5 minutes.
When the chili is done, carefully taste and add any salt/pepper, as needed. Remove the bay leaves. Serve immediately or refrigerate/freeze, as needed (be sure the chili is fully cooled before refrigerating/freezing). Enjoy!
